I received Bryce 3D from the first issue of 3D World magazine for free. It is the MetaCreations version. I was wondering if someone has tried or if it's even possible to upgrade to a bought version of Bryce 4. Will the Corel Bryce 4 CD recognize the free installed Bryce 3D? Does the upgrade offer/conditions extend to the free version given away by 3D World Magazine? Am I making sense or have I horribly confused everyone? Any information would be greatly appreciated. - gdavis3d
